Answer:

Cone

Step-by-step explanation:

We are given that a triangle ABC .

We have to find that what shape is formed when a triangle ABC is rotated about side AB.

A given triangle ABC is a right triangle.

When we rotate the figure about side AB then the figure will be cone .The side AB will be height of cone and side AC will be radius of cone.

Hence, when a triangle ABC is rotated about side AB, the cone is formed.

Answer: Cone

Jillian baked 2 batches of cupcakes in 1/4 of an hour. How long did it take her to bake one batch?

Nadya [2.5K]

2 batches:1/4 which is 25 min.

so 1 batch would be half of that.

So just divide 25 by 2, which would get you 12.5

12 minutes, and 30 seconds.

Hope this helped~

A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?

kompoz [17]

Answer:

5.9 years

Step-by-step explanation:

We believe a better representation of the compound interest formula is ...

$V(t)=P(1+\dfrac{r}{n})^{nt}$

We want to find the value of t for P=1 and V(t)=2. We are told n=4, so the formula becomes ...

$2=(1+\dfrac{.12}{4})^{4t}\\\\\log{(2)}=4t\log{(1.03)}\quad\text{take logs}\\\\t=\dfrac{\log{2}}{4\log{1.03}}\approx\boxed{5.9\quad\text{years}}$

e-lub [12.9K]

Answer:

<u>The correct answer is 5/24 or 0.21</u>

Step-by-step explanation:

1. Let's review all the information given to answer the question correctly:

Science class in seventh grade = 4 girls and 4 boys

Science class in eighth grade = 5 girls and 7 boys

2. What is the probability that both students selected for the competition are girls, a seventh grader and an eighth grader?

These are independent events, therefore:

Probability of two independent events = Probability of A * Probability of B

Probability of both students selected for the competition are girls = 4/8 * 5/12

Probability of both students selected for the competition are girls = 20/96 = 5/24

<u>The correct answer is 5/24 or 0.21</u>
